_Nature_ has compiled several dozen of its “Points of View” columns into a [single list] that, if you were to work through it, be a reasonable introduction to graphic design. As I’ve said before, [design matters], so if all of that overwhelms you, then please do consider working with someone who has some experience in design. All your efforts to communicate your data and your analysis more effectively will provide a return, if only because you will undoubtedly glimpse new patterns, new possibilities for analysis while doing the design.
And, for the record, I like the architectural word *projection* better than *visualization*, which is probably still better than *infographic*.
